ACTUAL INDICATIONS TO ENDOSCOPIC LASER-THERAPY IN THE LUNG CANCER NON-SMALL CELL. lriezzetti M Department of Thoracic Surgery,University of WI& lan,Nilan,Italy. ,riore than half of the lung cancers,non-small cell,ce.n't be resected and the research of the best palliative treatment is actual.When the tumor is not resectable,is central and involving a main or a lobar bronchus and has an important intraluminal component,the andoscopic laser-the rapy,looking at evaporation of the tumor and at reopening of the bronchus,has today a correct indication.From darch 1987 to January 1993 306 patients have been treated,1089 applications in all.We have observed no complication related to laser,a reopening of bronchi,with a significant radiological modification in 75% of cases and on an average the period for bronchial reopening.i:sof 4 months.1 think that ,in specified cases,as before remembered,laser therapy give good results. 897 TREATMENT AND RESPONSE OF SUPERIOR VENA CAVA SYNDROMEDUE TO MRLIGNANT TUMOURE.

In the present study we reviewed the response rate and survival of such svndrome after treatment with radiotheraov and/or chemotherapy. Material 18 patients were included and evalu&d. ble 16 female 2. Performance status >60%. Median age 57(37-811. Histologically were 3 small cell lllno cancers. 8 non-small cell luno cancer.1 thvmoma. 12 pati&s were'initially treated witg radiotherapi (Rt) Treatment (5; NSCLC, one thymoma)and 6with chemotherapy (4 SCLC and 2 NSCLC). Chemotherapy was Cis-platinum based combination. Response. Of 12 patients with Rt, 8 responded (66%), 3 of 5 SCLC, 5 of 6 NSCLC. 6 of 6 patients with chemotherapy responded (lOO%).Ona patient with thymoma did-not responde to Rt and responded to chemotherapy. Response was considered objective reduction of measurable turnour and also Median survival was 9 months reduction of superior vena cava signs. (3-20+). Chmotherapy may be equally effective as initial treatment Conclusion: of superior vena cava syndrome due to small cell lung cancer, non-.small cell lung cancer and thymoma as radiotherapy,if not superior.

From March 1991 to February 1993. 72 patients (pts) with Stage IIIb-IV NSCLC and non prior treatment were randomized to receive combination chemotherapy as follows: Arm A: IF 2500 mglm2 IV, day 1 and 2; Mema 20% of

PHASE II TRIAL WITH WEEKLY CISPLATIN (CDDP) AND CONTINOUSLY ORAL ETOPOSIDE (VP-161 IN ADVANCED NONSMALL CELL LUNG CANCER (NSCLC). R. Looez, Ft. Fernandez, J.A. Virizuela, J. Cueva, E. Garcia, A. Sanz, J.J. Valerdi, J.M. Gracia. Hospital de Navarra; Hospital de Cabuenes; Hospital General de Huelva, Hospital Central de Asturias; Spain. We performed a phase II trial with VP-l 6 50 mg/m2/day po day 1-21 q28 and CDDP 35 mg/m2 iv day 1,8 and 15 q28. Forty three untreated patients (ptsI(38 male/5 female) with histologically proven and inoperable NSCLC were included. All pts had evaluable disease by CT scan. Median age was 57 years (range: 33-70). Stage IIIA 4 pts, stage IIIB 18 pts and stage IV 21 pts. Histology was squamous 22 pts, adenocarcinoma 17 pts and large cell/poorly differentiated 4 pts. Performance status WHO O-l, 32 pts and WHO 2, 11 pts. 3 pts were not evaluable for response (2 death of intercurrent disease, 1 lost follow-up). A median of 3 cycles was given (range l-8). The response rate was 50% (20/40) (95% Cl: 35%-65%) with 3 pts achieving complete response (7.5%). On stage IV overall response rate was 45% (g/20)(95% Cl: 24%-66%). Severe toxicity (WHO 3-4) included leukopenia 16% of all pts, anemia 9%, diarrhea lo%, mucositis 14%. Nausea/vomiting grade 1-2 in 40%. Alopecia grade 2-3 was common (90%). We conclude that this ambulatory regimen was well tolerated and achieved a promising response rate. A phase Ill study is warranted.
PHASE II STUDY OF TOPGTECAN lN PATIBNTS WITH NONSMALL CELL LUNG CANCER.J+ez-SW, Glisson BS, Rane J, Raber MN, Hong WK. M.D.Anderson Cancer Center, Houston, TX. Topotecau is a hydmsoluble semisynthetic analogue of camptothecin undergoing extensive clinical evaluation. A Phase II clinical trial of Topotecan in patients with metastatic non-small cell lung cancer previously untreated is in progress. Topotecan is administered i.v. as a 30 min daily infusion for 5 consecutive days at a dose of 1.5 mg/mVday. Twenty one patients have been entered into the study. Fin patients are evaluable for response and toxicity. Characteristics of evaluable patients are as follows: h&&gy: sdenccaminoma 7, squamous cell carcinoma 3, poorly differentiated carcinoma 4, bronchioalveolar carcinoma 1; Dcrformancc: 0.3 patients, 1,12 patients. Two patients (13.3%) have achieved a partial remission (50% reduction in measurable disease for 24 weeks), 3 patients (20%) a minor reponse, 3 patients have remained stable, and 7 patients have shown progressive disease. From a total of 52 courses given, grade 3 or 4 toxicity has been limited to myelosuppression (predominantly granulocytopenia) lasting <7 days in most patients; two epidoses of neutropenic fever mqriring hospitalization have been recorded other toxicities include alopecia in most patients and grade 1 or 2 nausea and vomiting in about 50% of patients. Although preliminary, these results indicate that Topotecan has moderate activity in non-small cell lung cancer and is easily tolerated. Accrual will continue up to 40 evaluable patients.
